Product Description

This part includes one OEM O-ring for a nailer. The O-ring creates an air-tight seal around the piston stem. When O-rings fail this will hinder the performance of the nailer and may prevent the driver from returning. Since you will need to disassemble the nailer to access this O-ring, it is also a good idea to inspect all O-rings and replace them as well. If one is failing, it is likely that the others will be soon to follow. You may require some grease when installing your new O-ring.
